Question

Describe the mechanisms for ensuring cross pollination in detail please. ?

Answer 1

Pollination in plants is of two types: self-pollination and cross pollination.
Cross pollination is the transfer of pollen from the flower of one plant to the flower of a plant having a different genetic constitution.
The main mechanisms for ensuring cross pollination are:
1 Imperfect (or unisexual) flowers and monoecy.
2 Imperfect flowers and dioecy.
3 Dichogamy.
4 Chasmogamy.
5 Hercogamy(or herkogamy).
6 Self-sterility or self-incompatibility.
